analyze and interpret data to draw meaningful conclusions
about public health issues. By using these methods, public
health professionals are able to make evidence-based
decisions and implement effective interventions.
2. Question: Explain the concept of statistical significance
and its significance in public health research.
Answer: Statistical significance refers to the probability
that observed differences or relationships in data are not
due to chance. In public health research, statistical
significance helps determine the validity of study findings
and provides evidence to support or reject hypotheses.
3. Question: How do confidence intervals contribute to the
interpretation of study results in public health research?
Answer: Confidence intervals provide a range of values
within which the true population parameter is likely to fall.Â
